Abstract (en)
The thermostat device is installed in a coolant circuit of an engine (1), and is provided with an operating member (7) containing a thermal expansion element (15) which expands and contracts according to a temperature change of coolant to change a longitudinal length of the operating member (15) due to thermal expansion and contraction thereof so as to open and close a valve in the coolant circuit. The thermal expansion element (15) includes a first thermal expansion element (15a) with a lower thermal expansion start temperature and a lower thermal expansion response speed, and a second thermal expansion element (15b) with a higher thermal expansion start temperature and a higher thermal expansion response speed.
